Easily the most boring lesson was History of Magic, which was the only class taught by a ghost. Professor Binns had been very old indeed when he had fallen asleep in front of the staff-room fire and got up next morning to teach, leaving his body behind him. Binns droned on and on while they scribbled down names and dates and got Emeric the Evil and Uric the Oddball mixed up.
Haha, good one.
FYI, he wasn’t a ghost when he was hired though:
